This study reports the contribution of maternal general ability, some developmental milestones, early motor development, language development, and experiences, to intelligence as measured at age 5. Results confirm that there is a relatively low level of prediction of intelligence. (Author/KC)

Two methodological issues involved in determining the relationship between learning and general intelligence were examined: (1) the use of learning strategies in a paired-associate task and (2) the importance of time (rather than errors) in the measurement of learning efficiency. (Author/RD)

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)
